As the others have said a lot of what you describe fits the description of siymptoms of anxiety and depression PLUS a whole lot of other medical condtions. The other thing is that many of them are subjective, there is no hard and fast way to test for them or to quatify them, Dr's are often loathe to amke a dx based soley on such subjective kind of complaints, thats why they are looking for the more objective signs such as LP, evidence of ON etc. Also if you do have MS, remeber that over 85% of us have RRMS, so symptoms/signs can be harf to find unless you are in an active relapse- its a bit like having an intermittent fault in an appliance ( sorry for the analogy) but the appliance acts faulty until the repair turns up then its fine- it can be very frustrating - but eventually the problem will declair itself. When i first started having symtoms they were thinking of an autoimmune problem. possibly lupus but could not give me a dx so i too was in limbo- i was told that very same line- Whatever it is, it will eventually become more evident- its toughm but you need to be patient. The dr's will not be helping you one bit if they rush in giving you a dx that is not correct. as the other have also said, any chronic disease tends to have an emotional content such as anxiety depression, so it would pay to address that rather than try to shrug it off - you would not be human if this was not having some effects on your anxiety levles
